This one is a bit better, as it leaves SSE/2 enabled on targets that
support it.
Description: Conditionalize SSE and SSE2 support
This makes sure it builds compatible binaries also on
machines which have sse/sse2. Fixes the SIGILL bug.
Checks for DEB_HOST_ARCH_CPU!=i386 before tests are attempted.
Will try to use SSE/SSE2 on all other architectures.
Generated Code will still need MMX support to run.
